IMPROVEMENT IN TAPS FOR OIL-CANS.

The Scheule referred to in these Letters Patent and making part of the lame.

I, Jansz A. Bos'rwicn, ofthe, city, county, and State of NewYork, have invented an Improved Tap for vPetroleum-Gans and other vessels; ot' which the following is a specification.

Nat-ure and Objects of the I ncention.

My invention relates to the combination, with a can r other vessel for packing and transporting liquids, of a tap consisting of a hollow valve, provided with a discharge-spout or tube, and made t-o revolve upon a central pin over a suitable seat formed in the top of the can, the bottom of the valve and its seat being each pierced with apertures so placed and of such equal size as that, by a revolution of the valve, they may be brought into register to open communication through the same between the discharge-tube and the interior of the can- The object of my invention being to provide a close', tight stopper for the mouth of a can to be used for transporting and storing petroleum and other liquids, and to combine therewith a ready device for the discharge of any portion of itsV contents in a neat and satisfactory marner.

Description of the Accompanying Drawing.

Figure 1 is a top view, in perspective, of a portion 0i a metallic can having one form of my improvedl tap combined therewith, illustrating the same vwhen reversed and consequently closed Figure2 is a longitudinal central section through the closedtap shown in iig. l;

Figure 3 is a top view, in perspective, of a portion of a second can illustrating a modification of my improved tap in position when open, showing a spring combined therewith; and

Figure 4, a longitudinal central section through said open tap.

General Description.

A is a can or other lvessel for storing and transporting petroleum oils or otherliquids.

B is a seat, of cork, wood, leather, rubber, or other suitable packing material, litted and secured in a metallic cap-plate, C, disbed or made cup-shaped to receive the packing, and which is soldered or otherwise secured upon the mouth of the canor vessel A, as illustrated in the drawing,I gs, 2 and 4.

This cap and seat C B are perforated with a single aperture, d, fig. 4, and, see dotted lines g. 2, pierced at a point removed from the center thereof toward the nearest corner orxedge ot' the can.

E is a bolt or pin secured centrally to the cap-plate O, so as to project upwardly therefrom. through the packing B, and'whose upper end is threaded to receive a nut, F.

G is a hollow valve or disk, having its lower face dat and even to tit closely and accurately upon the seat B on .the cap-platel covering the mouth of the can A.

vIn its simplest form it is simply a cylindrical, Hatfaced metallic box having apertures pierced centrally through each face to receive the bolt or pin E projecting centrally from the cap-plate C. It revolves freely upon said pin E, and is secured thereon and held closely down upon the seat O by means of a nut, F, screwing upon the upper end of the piu or holt, as illustrated in figs. l and 2. It-is provided with a tube or spout, H, projecting from the side thereof at any suitable angle, but, by preference, at right angles, to its axis, and which opens into the interior thereof, as fully shown in fig. 2; and its lower face k, bearing upon the seat B of the cap-plateG, isperforated at a point, t', so removed from its axis as to register exactly with the aperture d pierced through said cap-plate and seat when it is swung around over the same.

The spout H serves as a handle to turn the valve either to bring the aperture i in register with the apv lerture d.` as shown in iig. 4, (see dotted lines, lig. 1,)

and thus open communication between the interior ot' the can and the interior of the valve G, to permit a discharge of the contents of the former into and through the valve and its spout H, or to reverse it, and thus close the openings fi d and seal the can, as shown in iig. 2.

From'the position ofthe aperture 'i in the cap-plate .with reference to thecorner of the can, the apertures i d are brought into register, and thus opened to form a direct channel only when the' spout H is turned, so

as to project over said corner,.as shown in tig. 3, and remains tight-ly closed when the spout is turned back over the top ot' the can, as shown iu fig. l. Instead oi makingthe valve G siinply drum-shaped, as shown in figs. 1 and 2, it may be made annular or part-ly annular iii-form0 In such case its lower face is made, as before, to' consist of a flat disk or plate, k, fitting closely down upon the `seat C on the cap-plate B, and centrally perforated to receive the pivot-holtE projecting therefrom; but its upper face is recessed, so as to leave an annular chamber', m, about its center, the central recess n being made either so deep as to rest upon the lower plate lo, or'clse Iliade to approach it simply, leaving an open spacc'or chamber, r, between the plate 7c and the plate forming the bottom of the recess, as illustrated in iig. 4; ofthe drawing.

The'upper end o1 the pivot-bolt E projects luto the recess n, and the nut F thereon lies wholly within said recess, which may be made, as betbre described, deep enough to admit also of the interposition of a spring, u, between the nut and the bottom tluireo'without causing the nut to project-above the upper face ot' the valve,y as fully illustrated in figs. 3 and of the draw ing.

Vent 'apertures .'may be pierced, if desired, inl-the upper face of the valve.

It is evident that the valve may he made angular instead of cylindrical, as'illustrated, and that the form and position of the discharge-tube or spout may be changed without departing from my invention.

Claim. I claim as'ny invention'- In` combination with eachother vand with a can or other vessel to contain liquids, the within-described hollow valve and discharge-tube G, and the seat G B for said valve, perforated andseeured to the vessel, all substantially as and for the purpose herein set forth.
